From Polyphasic Sleep Wiki
E2 was given by the Ubersleep Formula that details the Everyman schedules with the number of naps depending on the duration of the core sleep. It was presented a version of Everyman that is closer to mono than E3 is. It was originally called E4.5, to represent the core duration, but has since been renamed to E2, to represent the number of naps to maintain consistency between different schedule lines. In recent years, it has been a highly popular schedule, as it provides a significant sleep cut without being too inconvenient or difficult to adapt to.
